Job Summary

Description

The Microbiologist is responsible for performing microbiological testing accurately on time and in compliance with established methods aseptic practices and regulatory requirements. The role works across the microbiology workflow - from sample preparation through plating incubation reading and data entry - and contributes to media production instrument upkeep and a clean compliant lab.

Reporting to the Supervisor - Microbiology the Microbiologist executes routine and more complex microbial testing prepares media and samples operates and maintains instrumentation and records results with strong documentation discipline. This is a hands-on bench role that keeps the workflow moving while upholding the aseptic discipline and timing precision that microbiological testing demands.

We are looking for someone technically capable and detail-oriented - a careful process-disciplined bench scientist who executes accurately communicates issues early supports continuous improvement and helps develop less-experienced team members.



Responsibilities

1. Sample Preparation & Microbial Testing

  • Perform sample preparation - homogenization weighing and documentation of sample weights - for microbial analysis following SOPs.
  • Prepare media broths and agars; perform serial dilutions inoculate samples and incubate per method requirements.
  • Read and record plating results count colonies (manually and via plate reader) and calculate CFU/ g.
  • Support qPCR/PCR testing preparation and execution.
  • Organize label and store samples; prioritize preparation and retests based on testing schedules and deadlines.

2. Instrument Operation & Maintenance

  • Operate laminar flow hoods plate readers incubators PCR instruments and related equipment.
  • Perform routine maintenance cleaning calibration and diagnostics; record on bench sheets and incubation logs.
  • Monitor instrument performance during runs perform basic troubleshooting and escalate issues as needed.

3. Data Processing & Documentation

  • Enter and track sample data in the LIMS accurately and on time; upload data and confirm retest needs with Data Review.
  • Examine blanks and controls for contamination; spot-check calculations for accuracy and data integrity.
  • Record retests in the retest log and communicate sample delays to the Supervisor and Client Services.

4. Method Support & Continuous Improvement

  • Support the implementation optimization and validation of plating and microbial methods under the direction of the Supervisor.
  • Contribute to process improvements and testing efficiency.

Secondary Roles & Responsibilities

1. Lab Upkeep & Compliance

  • Maintain a clean sanitary aseptic workstation; complete daily and weekly cleaning tasks; dump samples and support disposal efforts.
  • Uphold environmental controls and contamination-prevention practices.

2. Inventory & Equipment Management

Monitor and audit stock levels of reagents consumables and instrument parts; perform and record routine pipette and dispensette checks; flag discrepancies to the Inventory team.

3. Collaboration & Additional Responsibilities

  • Work closely with the Supervisor and team and mentor and support less-experienced microbiologists.
  • Perform additional duties as the role evolves or as directed by the Supervisor - Microbiology or laboratory management.
